The working principle is as follows:
when the device needs to be used, a worker manually holds the handle to move the device to the position near the power tube, measures the power tube and marks a measuring point, then marks two sides of the measuring point according to the distance between the L-shaped cutting saw blade 5 and the end face of the circular cutting cylinder 1, so that the distance between the marking point and the measuring point is the same as the distance between the L-shaped cutting saw blade 5 and the end face of the circular cutting cylinder 1, the worker can manually hold the handrail 2, sleeve the circular cutting cylinder 1 on the power tube, move the circular cutting cylinder 1, and move the circular cutting cylinder 1 to the middle of the two marking points;
when observing that the mark point is aligned with the end face of the circular cutting cylinder 1, the worker loosens the handrail 2, so that the circular cutting cylinder 1 is placed on the power tube, then the worker holds the two adjusting handles 29 and simultaneously rotates the adjusting handles 29 towards the center of the circular cutting cylinder 1, and in the rotating process of the adjusting handles 29, the worker observes the position of the circular cutting cylinder 1 to avoid the circular cutting cylinder 1 from deviating;
and along with the rotation of the adjusting handle 29, the adjusting handle 29 drives the adjusting worm 27 to start rotating, and through the engagement of the adjusting worm 27 and the worm gear 30, the adjusting worm 27 drives the worm gear 30 to start rotating, and the engagement of the worm gear 30 and the adjusting gear grooved rail one 21, the worm gear 30 drives the adjusting gear grooved rail one 21 to start rotating, so that the annular adjusting frame 20 starts rotating, and the rotation of the annular adjusting frame 20 drives the adjusting gear grooved rail two 22 to start rotating, and through the engagement of the fixing lug 23 and the adjusting gear grooved rail two 22, the fixing lug 23 starts rotating around the fixing trunnion 24, so that the lower end of the fixing lug 23 is screwed out of the annular fixing groove 19, and along with the rotation of the fixing lug 23, the lower end of the fixing lug 23 starts to contact with the outer surface of the power tube, and through the continuous rotation of the fixing lug 23, the lower end of the fixing lug 23 gradually extrudes the power tube, the electric power tube is gradually aligned with the center of the circular cutting cylinder 1, after the fixing lug 23 rotates to a certain degree, the electric power tube is fixed completely, meanwhile, the center of the electric power tube is aligned with the center of the circular cutting cylinder 1, the rotation of the adjusting handle 29 is stopped, and the electric power tube and the circular cutting cylinder 1 are fixed completely;
meanwhile, the friction force between the fixing lugs 23 and the power tube can be effectively increased by the aid of the rubber cushions 25 on the fixing lugs 23, and meanwhile, due to the fact that the rotating directions of the fixing lugs 23 on the two sides of the circular cutting cylinder 1 are opposite, after the power tube is fixed, no matter the power tube rotates, the rotation resistance of the fixing lugs 23 on one side always blocks the rotation of the power tube, so that the power tube can be fixed before cutting, and can be fixed after being cut, and the cutting end face of the power tube is ensured to be even;
after the circular cutting cylinder 1 is fixed, the worker can connect the power supply access end of the stepping drive motor 11 with the external power supply, the stepping drive motor 11 starts stepping rotation, the stepping drive motor 11 drives the drive rotating shaft 12 to start rotating along with the rotation of the stepping drive motor 11, so that the drive rotating shaft 12 drives the bevel gear first 14 and the bevel gear second 15 to start rotating, the bevel gear first 17 drives the bevel gear seat 16 and the circular adjusting seat 8 to start rotating through the meshing of the bevel gear first 17 and the bevel gear first 14 and the meshing of the bevel gear second 18 and the bevel gear second 15, the bevel gear second 18 drives the bevel gear seat 16 and the circular cutting seat 4 to start rotating, the rotation directions of the circular adjusting seat 8 and the circular cutting seat 4 are the same due to the difference between the bevel gear second 18 and the bevel gear first 17, but the rotation speeds are different, so that after the circular cutting seat 4 rotates for one circle, at this time, because the rotation speed of the annular adjusting seat 8 is slow, the annular adjusting seat 8 moves reversely and slowly relative to the annular cutting seat 4, and in the process, the annular cutting seat 4 drives the L-shaped cutting saw blade 5 to move rapidly, the upper end of the L-shaped cutting saw blade 5 is inserted into the special-shaped saw blade adjusting groove 10, along with the difference of the rotation speed, the upper end of the L-shaped cutting saw blade 5 gradually moves to the deepest end in the special-shaped saw blade adjusting groove 10 to form the concave and shallowest end, and along with the movement of the L-shaped cutting saw blade 5, the L-shaped cutting saw blade 5 starts to rotate around the adjusting shaft 6 by the pushing of the special-shaped saw blade adjusting groove 10, so that the lower end of the L-shaped cutting saw blade 5 starts to extend out of the annular cutting seat 4, and the lower end of the L-shaped cutting saw blade 5 is screwed into the annular cutting cylinder 1;
the L-shaped cutting saw blade 5 is screwed into the annular cutting cylinder 1, the lower end of the L-shaped cutting saw blade 5 is in contact with the outer side surface of the power tube, the L-shaped cutting saw blade 5 rotates around the outer side surface of the power tube through the rotation of the annular cutting seat 4, so that the L-shaped cutting saw blade 5 performs cutting work on the outer side surface of the power tube, and the L-shaped cutting saw blade 5 gradually extends out along with the continuous work of the stepping driving motor 11, so that the power tube is gradually cut until the power tube is cut;
when the step driving motor 11 works for a set interval, the step driving motor 11 stops working, the staff disconnects the power supply access end of the step driving motor 11 from the external power supply, the lower end of the L-shaped cutting saw blade 5 reaches the maximum extension length before the step driving motor 11 stops working, namely the upper end of the L-shaped cutting saw blade 5 moves to the shallowest end of the special-shaped saw blade adjusting groove 10, then the L-shaped cutting saw blade 5 automatically stops along with the rotation of the step driving motor 11, the upper end of the L-shaped cutting saw blade 5 moves to the deepest end position of the special-shaped saw blade adjusting groove 10 again from the shallowest end of the special-shaped saw blade adjusting groove 10, the L-shaped cutting saw blade 5 loses the driving force of the special-shaped saw blade adjusting groove 10, the adjusting shaft 6 drives the L-shaped cutting saw blade 5 to reversely rotate through the elasticity of the clockwork spring 7, so that the L-shaped cutting saw blade 5 restores to the original position, so as to be completely retracted between the two annular cutting seats 4;
at the moment, the worker can manually rotate the two adjusting handles 29 reversely at the same time, and along with the reverse rotation of the adjusting handles 29, the fixing lugs 23 on the two sides of the circular cutting cylinder 1 rotate reversely, so that the fixing lugs 23 are separated from the power tube, and at the moment, the worker can draw out the power tube from the circular cutting cylinder 1 and take down the circular cutting cylinder 1;
and when the electric power pipe cutting work is carried out again, the staff only need repeat above-mentioned operation can.
In this device, adjust recess 10 and the cooperation that the L type cut saw bit 5 through heterotypic saw bit, make the L type cut saw bit 5 and can stretch out and reset work, can effectually avoid the device to cut the reset work behind the power tube to save the device time of cutting the power tube many times, the effectual cutting efficiency who improves the power tube.
The technical solutions described above only represent the preferred technical solutions of the present invention, and some possible modifications to some parts of the technical solutions by those skilled in the art all represent the principles of the present invention, and fall within the protection scope of the present invention.
